Analysis
The r7gd.12xlarge is a memory optimized instance in the r7gd series with 48 vCPUs and 384 GiB of memory on AWS Graviton3 (up to 2.5 GHz), which makes it memory-heavy at 8 GiB of memory per vCPU.
Within the same generation and size, the r7g.12xlarge on AWS Graviton3 costs $2.57/hour, 21% less ($508 a month). The other variants are the r7i.12xlarge at $3.18, the r7a.12xlarge at $3.65 and the r7iz.12xlarge at $4.46.
Running it in Mumbai instead of São Paulo saves $2,233 a month per instance: $2.11/hour against $5.17/hour, a 145% spread.
Compared with the previous generation, it costs 18% more than the r6gd.12xlarge on AWS Graviton2 ($366 more a month per instance), in exchange for the newer processor. The newer r8gd.12xlarge on AWS Graviton4 is 8.0% dearer at $3.53/hour.
On demand it costs $3.27/hour in US East (N. Virginia), $2,384 a month if left running, which puts it mid-table for memory optimized types at the 29th percentile per vCPU ($0.0680 per vCPU-hour) and the 42nd percentile per GiB ($0.00850 per GiB-hour).
It has local instance storage (2 x 1425 GB NVMe SSD), which is fast but lost when the instance stops. Network: 22500 Megabit.
Looking beyond its own line, 12 of 40 current types with 48 vCPUs and similar memory are cheaper. The cheapest of those is the r6g.12xlarge on AWS Graviton2 at $2.42/hour.
